The Chernobyl reactor was made using an extremely cheap design, cheaper than anything anyone else used.
>No heat exchanger, water was directly boiled by the uranium fuel
>no metal/concrete containment building for the reactor)
>instead of pressurized water they just used hollow graphite as the maintaining agent for the nuclear chain
>boron control rods were graphite-tipped too, which increases reactor output when inserted
And a whole host of other issues.
The actual cause? Inexperience from new and young recruits, a badly written procedure binder, followed by serious xenon poisoning.
Then the reactor went into a runaway reaction despite the xenon poisoning because they only had like 8 control rods in there. 15 was the minimum, and the reactor had about 220. Said graphite-tipped control rods were suddenly inserted all at once in a SCRAM procedure (basically shove everything in, in a last ditch effort to stop the reactor outright).
Reactor output peaked like flooring the gas pedal in a car. Control rods couldn't move further down. Pressure kept building until it blew a 450 metric ton lid clean off the reactor. Air and steam rushed into the core, reacting with the zirconium jacket of the fuel rods, creating a shitload of flammable hydrogen, causing a massive explosion that released a lot of radioactive material into the atmosphere.
